Acrodont

Acrodonty(from Greekakros'highest'^[1]+odont-'tooth') is an anatomical placement of the teeth at the summit of thealveolar ridgeof the jaw, without sockets,^[2]characteristic ofbony fish.Functionally, acrodont tooth implantation may be related to greater bite force.^[3]However, this result is not supported when size and phylogeny is taken into account.^[4]

Acrodonty in the Animal Kingdom

Squamata:Within squamate reptiles, acrodont tooth implantation is best known inAcrodontaand some species ofamphisbaenians,though some snakes are also referred to as being acrodont. Acrodonta is unique in that the name of the clade is based upon this trait. Most other squamate reptiles havepleurodontdentition, though some snakes are occasionally described as having acrodont dentition.^[5]^[6]

Rhynchocephalia:Acrodont tooth implantation is common withinRhynchocephalia,includingSphenodon.^[7]

Amphibia:Acrodont tooth implantation also present in somefrogsand thetemnospondylMicroposaurus.^[8]^[9]^[10]
